How much antifreeze does it take to winterize your RV? I have a 2008 Flagstaff 831BHSS and the dealer told me 2 gallons. I probably wasted a little, but it took 5 1/2 gallons to get the pink stuff flowing at all outlets. Almost forgot the outside shower. Also forgot to remove the filter so that is another $33 (dealer price). Can these filters be purchased anywhere other than the dealer?

Yes, the hot water heater has bypass valves. Thought at first I goofed, but took out the plug and it was empty. I was just surprized that it took so much after the dealer said 2 gallons. Got curious about others.

Forgot about the tanks! What do you recommend--1/2 gallon per tank--more,Less?
What about some in the tank dump drains? It usually don't get all that cold here in southwest Arkansas, but we do have several days below freezing, like 22-25 and even some times a day or two in the teens. I don't want to be embarrassed come spring when I want to go camping, that is RVing. Got to learn all this lingo.

Thanks for the filter info guys. We new guys have to ask a lot of questions. I'll check out the different places and see what I come up with. The 3 bux sounds more like my price. I don't mind paying a fair price, but I don't like getting ripped off either.

I have never used any antifreeze for winterization. Being that I am a plumber, I cut a T in line under the kitchen sink with a connection for an air hose. I also have installed ball valves at both drain points of the RV. I hook the hose up to it, turn my air compressor down to 50-60psi (max recommended rv pressure), and go around and open up all the taps one by one hot and cold and all valves and i'm done. You then leave all faucets open for expansion in case there is a tiny bit of water anywhere. I then dump -35C windshield washer fluid in the traps (1/2 as cheap as rv antifreeze) and giddy-up. Dis-connect my pump and put it inside with my battery. 10 min Max. I would not recommend doing this for everyone. I have done this in three rv's and have never fixed a burst line, then again even if one burst for me it would not be a big deal. Sucks to think that here I winterized almost three months ago....................uuugg.
